Which of the following fibers is hydrophilic?Question 9Answera.Polypropylene b.Polyesterc.Woold.Teflon (polytetrafluoroethylene or PTFE)e.acrylic

To determine which of the given fibers is hydrophilic, we first need to understand the term "hydrophilic." Hydrophilic fibers tend to absorb water and have a strong affinity for water molecules.

Analysis of the Options

1. a. Polypropylene: This fiber is hydrophobic, meaning it does not absorb water and is often used in applications where moisture resistance is important.

2. b. Polyester: Similar to polypropylene, polyester is largely hydrophobic and does not naturally absorb water.

3. c. Wool: Wool is a natural fiber that has hydrophilic properties due to the presence of protein (keratin) in its structure. It can absorb moisture without feeling wet.

4. d. Teflon (PTFE): Teflon is another hydrophobic material, known for its non-stick properties.

5. e. Acrylic: Acrylic fibers can be somewhat hydrophilic, but they are primarily considered hydrophobic.

Final Answer

The hydrophilic fiber among the given options is c. Wool, as it can absorb moisture effectively.
